Intel Lynnfield Core i7-870 and ASUS P7P55D - Benchmarks: SuperPi, wPrime

SuperPi and wPrime are pure mathematical tests and puts a big load on the processors. These are highly synthetic tests that have never worked well for AMD, but it could still be an interesting comparison between Core i7-870 and Core i7-965.

SuperPI

i7-965 (3.20GHz)
  12.266

  13.104
 
Phenom II 965 (3.40GHz)

SuperPI
32M [s]
i7-870 OC (4.00GHz)
  570.119
 
i7-965 (3.20GHz)
  668.469

Phenom II 965 (3.40GHz)

SuperPi is single-threaded and does not utilize the extra cores or HyperThreading support. Despite that we can see that Core i7-965 keeps a margin to Core i7-870, which is most likely because of the higher memory bandwidth, which plays a big role in this tests.

wPrime is, unlike SuperPi, multi-threaded and starts a process for each physical and virtual core. In other words, four threads for Phenom II, and eight threads with the two Core i7 processors with HyperThreading enabled.

Once again AMD has a hard time keeping up, but interestingly Lynnfield actually collects the victory in the 32M tests, which is really impressive and a bit surprising since Turbo Boost should not kick in here.

Moving on to less synthetic tests.
